OSCAR JOSEPH SIGLER, OF MANSFIELD, AND HENRY JEROME JARVIS, OF TOLEDO,

OHIO.

PEAT-EXPRESSER.

Be it known that we, OSCAR JOSEPH SIG- LER andHENRY JEROME JARVIS, citizens of the United States of America, residing, re-

spectively, at Mansfield and Toled0,in the counties of Richland and Lucas and State of Ohio, have invented certain new and use-- ful Improvements in Peat-Expressers, of

which the following is a specification.

.This invention relates to certain new and useful improvements in peat expressers, and

the object of the invention is to provide an improved and simplified apparatus of this type in which the expressing operation may beefl'ected with certainty of action.

Further and other objects will be laterv set/forth. a

In the drawings: Figure 1, is a side elevationof the apparatus, Fig. 2, is an en larged sectional v1ew taken on the line 22 of .Fi 3 Fig. 3 is a top lan view Fig. 4 is a aginentary detail view/of the flights and Fig. 5,! is an enlar ed sectional view taken on the line 5-5 0 Fig. 4.

The apparatus includes'a frame formed to have a base 1, and. end uprights 2. Longitudinal I-beams 3, are rigidly connected to the uprights 2, and are located on opposite sides of the frame. A transverse shaft 4, is journaled in bearings that are carried by the beams3, at the front end of the frame, and a pair of spaced toothed wheels 5, are rigidly mounted on said shaft. A transverse shaft 6 at the rear end of the frame isjournaled in bearings that are carried by-beams'3, and a pair of spaced toothed wheels 7, are rigidly mounted on said shaft 6. Miter gears 8 are keyed to shaft 6, and mesh with similar gears 9, that are rigidly secured to the lower ends of shafts 10, the latter having squared portions 11, which project into sleeves 12,

the latter being slidable on the squared portions 11. The upper ends of the sleeves 12,

are rigidly secured to shafts 13, which have. the miter gears '14,- rigidly secured thereto,

rigidly afiixed to shaft 17. The shaft 17 is Specification of Letters Patent.

upper longitudinal beams 18,- the latter being mounted by means of the'bolt and slot connection 19, so that the beams 18 have an adjustable pivotal connection at their front ends. The rear ends of the beams 18, slide in guides provided by the brackets 20. Each beam 18* has a rigid depending rod 21, affixed thereto, which is encircled by coil spring 22, the latter abutting the bracket 20. and anut-23, on rod 21. 'Due to the presence of-the springs the free 'rearends of the beams will have a yielding action and will normally be drawn downwardly, the beams havingthe aforementioned pivotal connection 19 at their frontend s. i

A drive shaft23, has a pinion 24, and a pulley 25 rigid thereon, the pinion meshing with a gear wheel 26. Any suitable belt may connect with pulley 25, to drive the same.

Toothed wheels 27 are rigidly secured to 'a'shaft 28, that is journaled in bearings carried adjacent the front end of beams 18.

The expressing mechanism proper ineludes an upper and lower endless platform, the upper. platform being of less are rigidly connected to the flights 29,011' the inner faces ofathe latter, so that .the rollers will engage the toothed wheels 5 and 7 revolubly mounted on L-shaped brackets 32, I

and 27 f and 16-. The flights are connected at their ends by means of chains 33. -A pair of'spaced stationary lower beams 34 are provided, and upper stationary beams 35, are

likewise provided, these beams 34 and 35,

being secured on brackets 35 mounted on the shafts 6 and 17, respectively, and are for engagement with antl-friction rollers 36, that are carried by the inner faces of the two platforms.

The lower platform is provided on op 0- site sides' with overlapping pivoted slde plates 37 which are secured to theindividual 4 flights thereof and which receive the upper platform therebetween, as depicted in Fig. 2 of the drawings.

The pairs of beams 34 and 35 provide pressure rails, that is to say when the antifriction rollers 36, engage said rails, as shown in Fig. 2, they will limit the movement of the confronting portions of the platforms and will act as abutments which hold the platforms to their work, effecting the expressing action on the material, in an ob- V1011S manner.

Bothplaforms have their confronting portions covered with a suitable fabric, or cloth and the liquid is forced through the foraminous lower platform by the upper platform. The cloth designated 38, is endless and passes around upper end rollers 39, lower rollers 4:0, and intermediate rollers 41. The endless bands of cloth are driven by friction existing between the same and the material which is being carried along, during the expressing thereof, by the upper and lower platforms.

From the above it will be seen that the liquid is forced through the cloth of the lower platform by virtue of the pressure exerted by the upper platform, and that the upper platform is capable of having a yielding up and down movement, due to the pivotal mounting of the beams 18 which support'the upper platform. It will fur-' ther be seen that the endless bands of cloth by reason of bein mounted on the rollers shown and described, will not interfere with the free movement of the platforms. The solid matter remaining at the completion of the expressing operation is delivered at the rear end of the apparatus and the liquid drops into a pan'42 that is secured on the interior of the lower of the platforms and is supported by the frame in any suitable manner. The plates 37 provide side walls which are located on opposite sides of the lower platform, preventing the solid matter from escaping in an obvious manner. The cloth further serves the purpose of preventing the solids from adhering to the platforms and further covers the interstices between the individual flights.

In operation the material is laced in the front end of the apparatus tween the platforms, and as the confronting faces of the platforms are forced toward one another by reason of .the rollers 36 of the platforms travelin on the tracks 34 and 35, the material will subjected to the pressure exerted by the platforms, and the liq-; 'uid will be expressed from, the solid matter and will drop into the pan. It will be un-- dcrstood that power imparted to the pulley 25 will drive the shaft 23 and therewith beams, a sprin gear 24, the latter rotating gear 26 and therewith shaft 6, which will cause rotation of the toothed wheels 7 and thereby efi'ect movement of the lower platform. The rotation of shaft 6 will cause rotation of the miter gears 8, and the latter by virtue of being in mesh with the miter gears 9 will drive the gears 14 and therewith the gears 15 of shaft 17 effecting movement of the upper platform by reason of the toothed wheels 16 being carried by the shaft l7.

Owing to the sliding connection between the shaft 10' and the sleeve 12' of shaft 13, the beams 18 are capable of rising and falling movement without disturbing the operatlon of the upper platform, in' an obvious manner. a

What is claimed is:

1.
